Quinlan Partners provides business intelligence, investigative due diligence, investigative and advisory services to law firms, corporations, investors, financial institutions, boards, and private equity sponsors facing critical business decisions, transactions, disputes, and compliance matters.
Facts, evidence, and investigative intelligence that inform critical decisions and influence outcomes.
Clients engage the firm when they require intelligence beyond publicly available information. The team combines investigative interviewing, source-level inquiries, public records research, open-source intelligence, and strategic analysis to help clients assess risk, evaluate counterparties, understand complex situations, and develop facts relevant to legal, business, and investment objectives.
We support investigative due diligence, civil litigation support, white-collar defense matters, internal investigations, asset tracing, international arbitration, and shareholder activism and proxy contests, many involving cross-border issues, multiple jurisdictions, and complex corporate structures.
A significant portion of the practice focuses on identifying legal, financial, operational, reputational, and governance risks before transactions or strategic decisions are made, where independent information gathering is essential. The firm also develops evidence, identifies witnesses, and uncovers facts that inform case strategy, strengthen positions, and support dispute resolution.

Quinlan is incredibly diligent - they get to the bottom of everything. They are resourceful and creative and they come up with solutions to difficult tasks.
Quinlan Partners has proven to be extremely responsive, transparent in the scope of their services and costs, and have provided services that demonstrate their incredible attention to detail.
The team at Quinlan Partners has diverse backgrounds giving them a deep understanding of the issues and interests facing clients. Independently, each member of their team was incredibly capable, and their team composition results in each team member enhancing the work of the others.
Quinlan Partners pursued their research and investigation through non-traditional means and used sources that I assumed were unavailable. They did so efficiently and delivered a concise report of their findings.
